What does "down the line" mean?

Great question. The phrase "down the line" is an idiom. It is used to mean that something happens at a further, later, or unspecified point. So, if you say that something happens "down the line", it happens at a later stage of a situation or activity. Note that you can also talk about something happening "a long way down the line" to emphasize that is will happen at a much later date. You can also include about a particular amount of time down the line, if you are talking about it happening after that amount of time. Ex: I think that is something that will happen down the line. Ex: He knows that a promotion is a long way down the line. Ex: About five to six months down the line I will give her a call.

In English, it seems there's a lot of figurative speech about the tree. Why is that?

In mythologies, legends, and novels, trees represent "growth" and "life." Trees are easily referenced for symbolism and meaning. It also centers on a lot of religions like Christianity, where one of the first bible stories is about the tree in the garden of Eden. I don't think there's one specific reason as to why trees are used a lot figuratively, but rather that trees are a part of nature, and thus part of the human experience. So inspiration is taken by nature and living things that humans live in and around!
